Description

Technical Field

[0001] The present invention relates to the field of rocket force training, and in particular to a comprehensive training platform and method for solid rocket electrical connectors. Background Art

[0002] The operation of electrical connectors has a crucial impact on the test launch of solid rockets. It has high requirements for the operating ability of the post personnel and is an important link to ensure the stable entry of solid rockets into space. There are many tasks that require the operation of electrical connectors during the test launch of solid rockets. The time span is throughout the whole process; the location involves the rocket and the ground; the stage involves the preparation of the state before the test; the scale covers single machine, system internal, and system between systems. Therefore, highly skilled electrical connector operators are an important factor in the success of solid rocket test launches.

[0003] At present, a certain launch site has a plug-in training platform developed jointly by the launch site and the Fourth Academy of China Aerospace Science and Technology Corporation in 2006. It is equipped with more than 70 electrical connectors, including circular snap-on type, circular threaded type, circular push-pull type, rectangular secondary hook locking type, buckle type, and rectangular handwheel type, which basically meet the training needs of liquid rocket electrical connector operations.

[0004] Due to the large differences in the types of electrical connectors for solid and liquid rockets, the existing plug-in training platform lacks the main types of electrical connectors for solid rockets, and cannot meet the professional training needs for electrical connector operations for solid rockets such as CZ-11 and KZ-1A. In addition, its training conditions are relatively ideal, which is simple plug-in training in an open space, and cannot achieve high-difficulty electrical connector operation simulation training under complex conditions on the rocket. As a result, when actually operating on the rocket, due to the influence of operating space and posture, the post personnel are prone to low operating efficiency and even operating errors.

[0017] There are multiple plugs arranged on the panel, and an indicator light is installed 3 cm above each plug;

[0018] The power connector 5 is located at the lower right of the comprehensive training platform. The power connector 5 is connected to a 220V power supply. A power switch 7 is installed above the comprehensive training platform. The power switch 7 can control the electrical system of the entire training platform.

[0019] The comprehensive training platform is installed on an independent platform, and the independent platform is connected and fixed with the training platform through the installation platform to achieve integration; or a lockable universal wheel 4 is installed at the bottom of the independent platform;

[0020] It also includes an electric connector, which includes a connector end and a socket end, and the socket end is a plurality of groups of plugs.

[0021] A further technical solution of the present invention is that it also includes multiple groups of plug-in cables, which are bidirectional plug-in cables that can be inserted into plugs. The multiple groups of plug-in cables and the corresponding plugs constitute a connector series circuit, which is connected to a DC power supply and a manual switch, and is also connected to an indicator light.

[0022] A further technical solution of the present invention is that the electrical connector is an electrical connector on a solid rocket.

[0023] A further technical solution of the present invention is that a lower panel 2 and an upper panel 10 are arranged on the platform body (1), and a plurality of sockets are arranged on the lower panel 2 and the upper panel 10 respectively.

[0024] A further technical solution of the present invention is that the two sides of the platform body (1) are hingedly connected to the anti-cheating plate 11 by hinges 12, and the anti-cheating plate 11 can be bent to the front end to form a relatively closed space to prevent cheating.

[0025] A further technical solution of the present invention is that a bracket 8 is arranged at the upper end of the platform body (1), and a camera 9 is arranged above the bracket 8.

[0026] A further technical solution of the present invention is that the electrical connector on the solid rocket is a CZ-11 solid rocket electrical connector or a KZ-1A solid rocket electrical connector.

Through the ladder diagram control program inside the PLC, its corresponding output terminal will also generate a high-level output signal, thereby driving the load circuit to be turned on and the LED indicator light is lit; on the contrary, if one or more pins in the electrical connector have poor contact due to misoperation, there is no signal input to the PLC input terminal, so that its output end cannot drive the load circuit and the indicator light is not lit; when the indicator light is lit, the invigilator can score the practical operation process of the assessable personnel according to the practical operation assessment standard of the electrical connector, and then manually enter the score into the assessment system software of the computer;

[0028] The PLC used is the S7-300 series PLC produced by Siemens of Germany.

[0051] Embodiment 1: In conjunction with all the accompanying drawings; a comprehensive training platform for solid rocket electrical connectors, characterized in that:

[0052] The platform body (1) of the comprehensive training platform is based on a steel structure as a basic frame, with a sheet metal part as a skin on the outer layer, the rear part is designed to be openable, and a steel structure frame is installed inside; a power adapter is installed inside;

[0053] There are 6 circular operation windows with a diameter of 15 cm on the front and sides of the comprehensive training platform;

[0054] There are multiple plugs arranged on the panel, and an indicator light is installed 3 cm above each plug;

[0056] The comprehensive training platform is installed on an independent platform, and the independent platform is connected and fixed with the training platform through the installation platform to achieve integration; or a lockable universal wheel 4 is installed at the bottom of the independent platform;

[0057] It also includes an electric connector, which includes a connector end and a socket end, and the socket end is a plurality of groups of plugs.

[0058] The substantial technical effects and implementation process of the technical solution hereof, i.e. the basic functions, are as follows:

[0059] The present invention aims at the problems that exist in the current solid rocket electrical connector operator training process, such as few solid rocket installation operation opportunities, single function of training equipment, and slow capacity building of post personnel. Specifically, the present invention can solve the following three technical problems.

[0060] Modular design of comprehensive training platform for electrical connectors

[0061] like Figure 1 As shown, the comprehensive training platform uses steel structure as the basic framework, sheet metal as the outer skin, and the rear is designed to be openable. A steel structure rack is installed inside to install electrical equipment such as power adapters. The preliminary design plan is as follows:

[0062] The comprehensive training platform for electrical connectors is 150cm long, 70cm wide and 170cm high. A total of 52 plugs are installed on the training platform (6 of which are inside the plug-in training platform for blind plugging), mainly distributed on two operating panels. Figure 2 For the panel layout on the comprehensive training platform, the center distance between the plugs is 14cm and the distance from the edge is 12cm. Figure 3 The center distance between the plugs on the lower panel is 20cm, and the distance from the edge is 15cm. There are 6 circular operation windows with a diameter of 15cm on the front and side of the comprehensive training platform, and a small indicator light is installed 3cm above each plug. The power connector is at the bottom right of the platform, connected to the 220V power supply, and a power start switch is installed above the platform to control the entire training platform electrical system.

[0063] It is installed separately on a small platform, and the installation platform is connected and fixed with the training platform to achieve integration. In addition, to facilitate the movement of the training platform, lockable universal wheels can be installed at the bottom of the platform.

[0064] Design of automatic reading system for connection status of electrical connector

[0065] The automatic reading system is used to evaluate whether the connection status is accurate during training and assessment. Due to the large number of electrical connector pins, how to design the internal circuit of the system and use the diode indicator to display the connector connection status is the key to the design of the system. Figure 7 As shown, it is planned to use S-type string line to connect all the pins in the electrical connection in series. If the connection state is not accurate, the pin and jack are in poor contact, the indicator light goes out, and the system judges that the connection operation is unqualified. The internal power supply is planned to use a power adapter plus a battery to convert 220V AC power into a low-voltage DC power supply. The battery can provide power for training when there is no or inconvenient external AC power.

[0066] The use of a human-computer interaction system and a database design for the training and assessment results of trainees is more conducive to the scientific and reasonable improvement of personnel's job operation skills. A human-computer interaction interface is embedded in the appropriate position of the panel on the comprehensive training platform, and personal training and collaborative training courses are recommended according to the personnel's professional skill level, with training teaching videos attached, so that personnel can carry out training more scientifically and reasonably. By storing personal training data in a database for statistical analysis, guidance is provided for subsequent training organizers to design training plans.

[0067] Based on the comprehensive training platform for electrical connectors, training and assessment are mainly carried out at three levels: basic operation training and assessment; operation training and assessment under complex conditions; and practical operation training and assessment.

[0068] (1) Basic training and assessment: training and assessment on basic operation essentials, test system, etc. are carried out under the conditions of broad vision and sufficient operation space;

[0069] (2) Setting up training and assessment in complex situations close to the actual situation on the arrow, such as narrow operating space and limited field of view;

[0070] (3) Closely follow the actual combat operation training assessment and integrate the comprehensive training platform into the battlefield environment. For example: use the human-computer interaction system to simulate different battlefield environments to train and assess the actual combat test operation ability of trainees; train and assess under the condition of personnel fatigue; modularize the comprehensive training platform to make it easy to disassemble, assemble and install flexibly, and then set it as one of the subjects of the field pull-up exercise to achieve close to the actual combat test training assessment, etc.

[0071] The present invention has the following advantages:

[0072] 1. Based on the CZ-11 and KZ-1A solid rocket electrical connector models, the design is based on the principle of operating in the real environment on the rocket and the goal of meeting practicality.

[0073] The platform carries a human-computer interaction system that can meet the actual needs of basic operation training and assessment; operation training and assessment under complex conditions; and actual combat operation training and assessment. It reduces the difficulty of training operators for solid rocket electrical connectors, meets the needs of capacity training, and can also be used as an assessment platform, realizing dual use of one machine.

[0074] 2. The platform has strong independent expansion capabilities, is easy to operate and easy to carry

[0075] The platform is designed with modular functions, which is convenient for later disassembly, assembly and expansion. Moreover, the platform has a simple structure, simple operation, and supports battery power supply. The battery power supply time (under normal training conditions) is not less than 5 hours. It is easy to carry and suitable for simulating various battlefield environment assessments.

[0076] The method for comprehensive training of solid rocket electrical connectors is characterized in that, by using the comprehensive training platform for solid rocket electrical connectors as described in any one of the above items, after the connector end and the socket end are connected through the connecting wire, the indicator light will light up; thus, it can be determined that the connection is successful, otherwise it is determined that the connection fails;

[0077] The connection status can be automatically judged, and the judgment system can display and archive it through the human-computer interaction interface;

[0078] This will enable rocket operation training.

[0079] Embodiment 2: As a further improved solution or parallel solution or optional independent solution, it also includes multiple sets of plug-in cables, which are bidirectional plug-in cables that can be inserted into plugs. Multiple sets of plug-in cables and corresponding plugs constitute a connector series circuit, which is connected to a DC power supply and a manual switch, and is also connected to an indicator light. The substantial technical effect of the technical solution here and its implementation process are as follows: the use of quick-plug cables can assess the proficiency of employees in ports and circuits, etc.

[0082] Embodiment 4: As a further improved solution or parallel solution or optional independent solution, the two sides of the platform body (1) are hinged with anti-cheating plates 11 through hinges 12, and the anti-cheating plates 11 can be bent to the front to form a relatively closed space to prevent cheating. The substantial technical effect and implementation process of the technical solution here are as follows: the anti-cheating plate 11 is unfolded to prevent employees from copying the side. When there is no need to prevent cheating, it can be leaned on the back plate. The back plate can be turned up, and an opening door can also be set.

[0083] Embodiment 5: As a further improved solution or parallel solution or optional independent solution, a bracket 8 is arranged at the upper end of the platform body (1), and a camera 9 is arranged above the bracket 8. The substantial technical effect and implementation process of the technical solution here are as follows: the exercise situation can be monitored.

[0084] Embodiment 6: As a further improved solution or parallel solution or optional independent solution, the electrical connector on the solid rocket is a CZ-11 solid rocket electrical connector or a KZ-1A solid rocket electrical connector. The substantial technical effect and implementation process of the technical solution here are as follows: CZ stands for Long March, and KZ stands for Kuaizhou.

[0085] Embodiment 7: As a further improved scheme or parallel scheme or selectable independent scheme, the connector series circuit is also connected to the internal circuit of the PLC, and the corresponding input terminal of the PLC will generate a high-level input signal. Through the ladder diagram control program inside the PLC, its corresponding output terminal will also generate a high-level output signal, thereby driving the load circuit to conduct, and the LED indicator light is lit: On the contrary, if one or more pins in the electrical connector have poor contact due to misoperation, there is no signal input to the PLC input terminal, so that its output end cannot drive the load circuit, and the indicator light is not on; when the indicator light is on, the invigilator can score the practical operation process of the assessable personnel according to the practical operation assessment standard of the electrical connector, and then manually enter the score into the assessment system software of the computer;
